elaboration of the protocol from measurements.
 
Learning outcomes of the course unit:
The main aim of this subject is to provide an introduction to the fundamental concepts of how noise and vibration can be controlled. The subject presents noise and vibration control primarily at the introductory level. As such, the subject should be of interest to students in engineering programs at the university level and to students in technology and technician programs at community colleges who need to acquire a basic understanding of noise and vibration control principles and applications; it should be of value to the practicing engineer who may have no formal training in noise and vibration control but whose responsibilities now involve assessment of noise and vibration and implementation of methods to control it.
 
Course contents:
The subject contains the methods of primary and secondary noise and vibration control. Specifically: transmission of waves, forces damped vibration, wave equation of longitudinal, transverse and torsional vibration, vibration of membranes and plates -- two dimensional equation, fundamental physical quantities of vibration, resonance, sources of vibration,
characteristics of acoustic vibration, levels, time signal, frequency spectrum, cepstrum, transmission of vibro-acoustic signal through surroundings, diagnostics model generating of vibro-acoustic signal, characteristics of signals and their transformation, reference frequency spectrum and reference mask, cepstral analysis, envelope analysis, speed frequency, severity vibration, detection of faults, condition and quality of the machines, sensing a analysis of vibro-acoustic signals, windows, sampling, filters, modal analysis, orbital analysis, detection of faults and reasons for different machines, transmission of vibro-acoustic vibration through structures, damping of mechanical vibration in structures, measurement of vibro-acoustic properties off resilient materials, resilient insertions, dynamic absorbers, sandwich structures, vibroisolation, properties of porous acoustics materials, resilient and vibroisolation materials, foam aluminium, European directives and legislative documents and standards about dynamic exhibition of machines, methodology of the measurement of vibration and noise, type and nature measurement, basic measuring system, microphone, sensors, multifunction analyser of vibration and noise, using the computers for signal analysis.
